Detailed Description

constructor from the trivial function with two argument

  double func( const double , const double ) ;

  const AbsFuction& fun = Adapter2DoubleFunction( fun ) ;

  // evaluate the function in point (1,2):
  Argument arg(2) ;
  arg[0] = 1 ;
  arg[1] = 2 ;

  double value = fun( arg ) ;

Parameters:

func	pointer to trivial function
